marks type-key levers, and 11 marks space-key levers. The levers 10 areprovided with finger-pieces 12 at their forward upturned ends, and thespace-key levers 11 are connected bya space-key 13, extending across thefront ofthe keyboard and limited in its downward movement by stops 14,secured to the front end of the frame 1. The key-levers 10, preferablystamped from sheet metal, are fulcrumed at their extreme rear ends upona rod 15. The front ends of the key-levers 10 are suitably spaced toaccommodate the finger-buttons 12, while in rear of the keyboard thelevers are bent inwardly toward the middle line of the machine for apurpose presently to be explained and at their rear ends are broughtclose together and parallel with each other, being confined againstlateral motion upon their fulcrum-rod 15 by two of the supports 16 forsaid rod. Immediately in rear of the keyboard the key-levers 1O fitbetween and are guided in their vertical movements bya series ofvertical pins 17, depending from the frame-bar 3 aforesaid. Forconvenience in assembling and to permit the easy removal of any one ofthe key-levers 10 without the others the rear ends of the levers areprovided with slots 18, opening into the holes through which the fulcrum-rod 15 passes, and the rod 15 is flattened upon its rear and frontsides and is so mounted in its supports that it can be turned aquarter-revolution to bring its flattened sides parallel with the slotsin the key-levers. The vertical thickness of the rod 15 when turned withits flattened sides parallel with the slots in .the keylevers is suchthat any of the levers may be readily disconnected from it by drawingthe lever forward, and the lever may be replaced with equal facility andthere secured in place by turning the rod up to normal position. Inoriginally assembling the parts of the machine the rod 15 may be put inplace before the keylevers are assembled and the latter be thenconnected to it in the manner indicated. The parallel parts of thekey-levers 10 at the rear of the machine form mutual guides for anykey-lever that is operated. It will be noted that the key-levers arefulcrumed at their rear ends and at right angles to a single axis or rodand that they diverge sharply toward the front of the machine and becomeparallel at the keyboard-space. The typebars 19 carry type-blocks 20,which in the instance shown are provided each with two types, as upperand lower case characters. The type-bars are arranged in the are of acircle in front of the platen 9 and intermediate the same and thekeyboard of the machine. The type-bars 19 are of uniform size and shapeand are pivoted at near their lower ends upon the inner rear ends oftype-bar hangers 21, which consistof thin plates stamped from sheetmetal and composed of an outer or forward horizontal portion and anupturned rearwardly-curved portion. The forward portions of thesehangers 21 are seated in radial slots formed in the upper side of asegment or an arc-shaped support 22, which is secured at its oppositeends to the main frame 1 of the machine. The plane of the segment 22 ishorizontal, and the typebar hangers 21 are so arranged that the pivotsof the type-bars are in front of and below the level of the axis of theplaten 9. The type-bars 19 are curved forwardly and upwardly of themachine and are of a length such that their type coact with the platen9, near the top thereof. The lower inner end of each type-bar 19 isconnected by a wire 23 to its corresponding key-lever 1O beneath it, andby means of the arrangement of the keylevers 10 shown in Fig. 2 andhereinbefore described the type-bars 19 may be connected to theircorresponding operating-levers 10 at points 24 immediately beneath suchtypebars, so that the connecting-wires 23,which,- it will be noted, arearranged in an are at their points of connection with the key-levers aswell as with the type-bars, are straight and of equal and minimum lengthand stand in an approximately vertical position, thus permitting adirect and approximately uni= form application of the power of all thekey levers to their respective type-bars. The pivots of the type-barsare arranged in a horizontal plane and preferably below the hori zontalplane through the printing-point. The are in which the type-bars 19 arethus piv= oted is in front of the platen, and the typebars flareupwardly and outwardly and rest in inclined positions relatively to thetop of the platen and are thus brought low down, with the type endsoccupying a larger are than the are formed by their pivots, by whichconstruction and arrangement the operator is enabled to view theprinting-point without craning the neck or moving from natural workingposition. The type-bar hangers 21 are held in place in.their slots 25 inthe segment 22 by the means shown on an enlarged scale in Figs. 4, 5,and 6, said figures being on a uniform scale larger than the scale ofFig. 3. The horizontal portion of each hanger 21, which fits in the slot25 in the frame 22, is of such width that its upper edge projectsslightly above the upper surface of said frame 22. The slots 25 areradial with the printing-point and are arranged in pairs, the members ofeach pair being closer to each other than either member is to a memberof an adjacent pairof slots. In other words, the walls 26, separatingmembers of the same pair of slots 25 from each other, are thicker thanthe walls 27, separating the members of adjacent pairs of slots. Thesegment 22 is provided with perforations 28, lying between the membersof each pair of slots 25 and passing through the walls 26, as shown moreclearly in Fig. 6. There is provided a flat plate 29 for each pair ofhangers, resting in each pair of slots 25, the said plate resting uponthe slightly-projecting upper edges of the said hangers and the saidplate 29 extending outwardl y beyond the edge of the frame 22. Bolts 30are passed upwardly through the openings 28and through the overlyingplates 29. The bolts 30 are provided at their lower ends with heads,which bear against the lower surface of the frame 22, and the bolts arescrew-threaded at their upper ends and have nuts 31 screwed upon them,which nuts bear on the tops of the plates 29. The wall between the pairsof slots 25, and so between the pairs of hangers 21, is slightly lessthan the diameter of the bolt 30, and the opposite sides of the bolt areflattened to permit its passage between the hangers, the contact of thehangers with the flattened sides of the bolt then holding the bolt infixed position while the nut 31 is screwed tightly upon its upper end,and the plate 29 is firmly clamped against the two edges of the hangersupon which it bears, thus securely holding them in place. The extremeouter ends of the plates 29 are provided with upturned cars 32, to whichare connected the outer ends of the coiled springs 33, which serve toyieldingly hold the type-bars in and to return them to normal position,the inner ends of said springs being connected to the type-bars atpoints outside of and slightly above their pivotal connection with thehanger-plates 21, as seen in Figs. 3 and 4. The friction of the pivotalconnection of the type-bars of the hangers is relieved by ball-bearings,the arrangement of which will be next described, reference being hadmore especially to Figs. 6 and 7. Each of the hangers-21 is provided atits upper inner end with a threaded hole into which is screwed one endof a short screw 34, whose head is beveled at its side adjacent thehanger and which is provided with a cylindrical body 35 intermediate thehead of the screw-threaded portion, said cylindrical body 35 being of adiameter greater than that of the screw-threaded portion. The connectionof the bar to the hanger affords a bearing for the type-bar whichoccupies very little space laterally and enables the entire series oftype-bars and hangers to be arranged in compact order in less thanone-third of a circle, while at the same time the comparatively largediameter of the bearing affords a rigid support for the type-bar againstlateral play and serves to preserve the alinement of the types. Anytype-bar and its hanger may be readily removed for the purpose oftightening up its screw 34 or for any other purpose by unscrewingthe'nut 31 upon the upper end of the bolt 30 adjacent such hanger andremoving the plate 29, which is held in place by said nut, and bydisconnecting the type-bar from its resetting-spring 33 andconnectingwire 23. The slots in the frame 22, in which the hangers 21fit and are secured, are truly radial to the printing-point, and inassembling the type-bars the alinement may be readily attained byadjusting the hangers 21 back and forth in the slots and then securingthem in place by means of the plates 29, bolts 30, and nuts 31. Thehanger 21 has formed upon its side adjacent the type-bar 19 a circularV-shaped groove 39 for the reception of the balls 37, the balls beingheld in place by the flat surface of the type-bar 19, which is providedwith a small hole fitting upon the screw 34. The type-bar 19 is alsoprovided with a slight circular boss 40, provided with a cylindricalbore, within which the cylindrical portion 35 of the screw 34 passes.The balls 37 are in a circle of a diameter greater than that of the headof the screw 34 and bear against the side of the type-bar 19. Under thisconstruction the type-bar is notsupported wholly upon the balls; but theprovision of the balls interposed between the type-bar and hanger in acircle concentric to the pivotal axis of the type-bar permits themounting of the type-bar upon a small pivot, as screw 34, so that thefriction between the type-bar and its pivot is very slight,while thecomparatively large circle of balls interposed between the type-bar andhanger furnishes a large bearingbetween the two to rigidly hold the typebar against lateral play without materially increasing the frictionbetween the type-bar and hanger. The desideratum sought is to reduce thelateral width or thickness of the bearing to a minimum in order topermit the most compact arrangement of the series of type-bars andhangers and at the same time provide a frictionless bearing of largediameter between each type-bar and its hanger to prevent lateral play ofthe type-bar and preserve the alinement. The hub portions of the hanger21 and the type-bar 19 may be re garded as a pair of plates. The conicalhead of the screw or pivot-pin 34 holds the typebarhub upon thepivot-pin and also cooperates with the bearing-balls to steady thetype-bar laterally in its swinging movement toward the platen. Theannular groove 39 is preferably of such diameter that the balls do notcontact with the pivotpin 34. Preferably the type-bar turns partly uponthe conical head of the screw 34 as a pivot and partly upon the shoulderor body portion 35 of the screw. \Vhen in normal position, the typebars19 rest at their outer edges against a curved type-bar rest 41,supported at its opposite ends upon the frame 22 by means ofdownwardly-extending arms 42.

The next feature of this branch of my invention relates to a movabletype guide adapted to be moved into and out of the path of the types atthe printing-point, and the same will next be described. The type-guideshown in the drawings comprises a frame 43,. provided with an elongatedopening or slot 44 of suitable size and shape to permit the passagethrough the plate of the types upon the ends of the type-bars and havingslightlybeveled walls to coact with the type-blocks to center the typeas they strike the platenroller 9. The frame 43 is pivoted at 45 in lugsor cars 46, extending forwardly and upwardly from a curved post orstandard 47,

which is attached to the frame 4, hereinbefore mentioned. The frame 43comprises a body having the guide-slot 44 and two downwardly-extendingarms 43, which are joined by a cross-piece 49, which is extended beyondthe arms 48 and is bent back parallel to itself, as shown at 49 in Fig.1, to provide a ribbongnide and also bearings for the pins or screws 45,hereinbefore mentioned. The cross-bar 49 is provided with a forwardlyand downwardly turned arm 50, to which the upper ends of two links 51are pivotally connected. The lower ends of the links 51 pass downoutside the two parallel standards 52, rising from the base of bracketor standard 47, and the standards 52 are provided with slots 53,extending upwardly and slightly rearwardly. The lower ends of the rods51 are united by a cross-pin or screw 54, which passes through the slots53 and forms an axis for a roller 55, which lies between the brackets52. A spring 56, having one end connected to one of the rods 51, nearthe upper end thereof, and the other end connected with the brackets 52,serves to normally draw the rods 51 downwardly until the pin 54 rests inthe bottom of the slots 53, thus holding the guide-frame 43 in theposition shown in Figs. 3 and 8. A lever 57 is pivoted at 58 between thestandards 52 aforesaid, the point or axis 58 being on a level higherthan the level of the lower ends of the slots 53, and the lever 57 isprovided with a curved notch or cam 59, adapted to coact with the frontand underneath portion of the roller 55 as the rear end of the lever 57is raised, and so to force the rods 51 frame 43 rearwardly toward theplaten 9 until such time as the circular end 60 of the lever 57 passesbeneath the roller 55, after which the continued motion of the lever 57exerts no further lifting action or power upon the rods 51, since thecenter of end 60 lies in the axis 58 of lever 57. A rod 61 is pivotallyconnected to lever 57 at its front end, and the other end of the rod 61is similarly connected to a cross-bar 62, lying underneath the keylevers10, said bar 62 forming the middle portion of a bail whose ends arepivoted to the frame 1 at 63.

The operation of the foregoing devices is as follows: Upon thedepression of a key-lever 10 its corresponding connectingrod 23 is drawndownward, thus drawing down the rear end of the corresponding type-barand throwing the type thereon rear-wardly and toward the printing-point,and at the same time the key-lever depresses the bail 62 and through therod 61 draws down the forward end of the lever 57, thus causing the camportion 59 of the lever to push the roller 55, pin 54, and rods 51upwardly against the force of spring 56. The endwise motion of the rods51 causes a rearwardly-swinging motion of the guide-frame 43 until suchtime as the dwell portion 60 of the lever 57 comes into coaction withthe roller 55, at which time the guide-frame 43 lies closely adjacentthe platen 9. The guide-frame 43 reaches the described position andcomes to rest under the influence of the spring 56 and the dwell 60before the type-bar has completed its printing movement; but thecontinued downward movement of the key-lever to bring the type on thesaid bar to the printing-point exerts no turning effect upon thetype-guide frame. As the type approaches the printing-point the guide 43coacts with the type-block 20 to center the type, which passes throughthe opening 44 and makes its impress upon the substance of the platen 9by means of an inkingribbon. Upon the release of the depressed key-leverthe springs 33 and 56, aided by the spring 64, connecting a universalbar 65 with the frame 4, restore the type-bar, keylever, and type-guideand hail 62 to normal position, and at the return movement of the partsthe type-bar moves forward in advance of the type-guide. Theinking-ribbon hereinbefore mentioned is marked 66 and is guided in anysuitable way to and between the crossbar 49 and the arm 49 at one side(say the left-hand) and upward in front of the bar 43 at that side andaround an edge 67 thereof and across in rear of the said bar 43 to asimilar edge 67 at the other side, at which point it passes to the frontand then down to and between the arm 49 and cross piece 49 at theright-hand side and away to a ribbon-spool. (Not shown.) In this mannerthe frame 43 also serves as a ribbon-guide; but this feature of myinvention is specific ally claimed in a companion application, filedApril 10, 1899, Serial No. 712,477. The construction of the lever 57 andthe arrangement by which it gives a uniform throw to the typeguide 43also serves to prevent variations in the movement of differentkey-levers from effectin g the throw of the type-guide. A more simpleconnection between the lever 57 and the vibratory type-guide would be topivot the lower end of the link 51 directly to the rear end of the lever57; but the described construction is preferable for the reasons juststated. Under the connection hereinbefore described, after any key-leverhas been moved a sufficient distance to cause the curve or cam portion59 in the rear end of the lever 57 to clear the roller 55, which it haslifted, it is immaterial to the operation of the typeguide whether suchkey-lever moves any farther or not, such farther movement having noeffect upon the type-guide. The form of connection shown also permitsthe type-guide to come to rest upon the platen-roll before the movementof the key-levers and type-bars ceases; but this might be accomplishedeven were the rod 51 directly connected to the lever 57. This feature ofmy invention is not restricted, however, to any particular connectionbetween the key-levers and type-guide for operating the latter. Thecarriage Sis drawn forward by a spring (not shown) and is provided witha rack-bar 68. The rear rail IIO 25 for the purpose describe 3o lel atthe keyboard-space, type-bars 50 between which the 6 is provided withstandards 69, in which a shaft 70 is journaled, and the shaft 70 isprovided with escape-dogs 71 ofany suitable construction and adapted tocoact with the rack A connection 72 between an arm on the shaft '70 andthe universal bar 65 communicates motion to the shaft and dogs whenevera key-lever is operated.
